Frog dissection via the world-wide web: Implications for widespread delivery of instruction

While valuable instructional products are available for development and distribution via a variety of media, the Internet provides one of the most effective delivery mediums to date. In this paper, we describe the design and development of a set of Internet-based instructional materials on frog dissection and anatomy, and report on the effectiveness of Internet delivery for encouraging high levels of use and user satisfaction.A previous version of this paper was presented at the 1995 annual meeting of the Internet Society, Honolulu, HI.     

Secondary Students' Dynamic Modeling Processes: Analyzing,Reasoning About,Synthesizing, and Testing Models of Stream Ecosystems

In this paper, we explore dynamic modeling as an opportunity for students to think about the science content they are learning. We examined the Cognitive Strategies for Modeling (CSMs) in which students engaged as they created dynamic models. We audio- and videotape-recorded eight pairs of ninth grade science students and analyzed their conversations and actions. In analyzing appropriate objects and factors for their model, some students merely enumerated potential factors whereas others engaged in rich, substantial, mindful analysis. In reasoning about their models, students discussed relationships in depth, concentrated only on the most important key relationships, or encountered difficulty distinguishing between causal and correlational relationships. In synthesizing working models, students mapped their model to aid visualization, focused on their goal, or talked about their model's appearance or form. Students attempted to articulate explanations for their relationships, but sometimes their explanations were shallow. In testing their models, some students tested thoroughly but only a few persisted in debugging their model's behavior so that it matched their expectations. In our conclusion we suggest that creating dynamic models has great potential for use in classrooms to engage students in thought about science content, particularly in those thinking strategies best fostered by dynamic modeling: analysis, relational reasoning, synthesis, testing and debugging, and making explanations.

Expanding the Foundation: Climate Change and Opportunities for Educational Research

Human-caused climate change is a dominant global challenge. Unlike other disciplines and fields, there has as yet been only limited attention to climate change in educational research generally, and in educational foundations in particular. Education is key to assisting humanity in mitigating and adapting to climate change, and educational researchers working within diverse disciplinary and methodological traditions and a broad array of research contexts need to engage in this most pressing of challenges. We argue that the field needs a new commitment to a form of educational justice appropriately scaled to the size of the challenge we face. We address this gap by reviewing current thinking on the human dimensions of climate change and summarizing what research has been conducted in the area of climate change education as a means of identifying a range of possibilities for educational research and praxis.     

Explaining the effects of communities of pastoral care for students

This article explains how communities of pastoral care work. It presents an empirically forged theory in action. We examined theoretical and empirical work across the targeted area of personalization for students. We also completed what Hallinger (2012) refers to as “exhaustive review” of the field of school improvement writ large. We treated the literature as qualitative data, inductively developing macro-level constructs, mid-level elements, and micro-level practices. We find that pastoral care for students has important effects on student learning. We conclude that the impact is mediated through two critical variables, institutional affiliation and student engagement.     

Simulation-based performance assessment: an innovative approach to exploring understanding of physical science concepts

This paper illustrates the use of simulation-based performance assessment (PA) methodology in a recent study of eighth-grade students’ understanding of physical science concepts. A set of four simulation-based PA tasks were iteratively developed to assess student understanding of an array of physical science concepts, including net force, acceleration, velocity, and inertia. Illustrative examples drawn from the administration of these simulation-based PA tasks to a sample of eighth-grade students (n?=?74) highlight the potential of simulation-based tasks for revealing conceptual understanding of science concepts and for informing curriculum development within the context of design-based implementation research. The paper also describes a variety of challenges encountered over the course of the development, administration, and analysis of the PA data that may be informative for researchers and educators as they consider implementing simulation-based PAs.
